i brought this up in another thread, but feel it deserves it’s own topic.
how about using black orc rules for immortals? str 4, great weapons or HW/S, or 2x HW, a 01 special choice to represent their rarity, and i think any one will agree that while not the most impressive special choice, they are certainly better than warriors w/ great weapons. the larger base provides for more dynamic poses.
the only problem i see here is ld 8. this is easily fixed with a bull centaur hero in the unit, or keeping them near a general.
